| x CMOS Low Power Consumption x Small Input-Output Voltage Differential: 0.1V at 100mA s Applications q Portable Cameras and Video Recorders q Battery Powered Equipment q Palmtops q Reference Voltage Sources w x Maximum Output Current: 1000mA x Output Voltage Range: 2V~6V x Output Voltage Accuracy: 2% s General Description The XC62E series are a group of positive output voltage regulators that can supply up to 1A of output current using an external transistor. Low power and high accuracy are achieved through CMOS process and laser trimming technologies. The series consists of a high precision voltage reference, an error correction circuit and a short-circuit protected output driver. In stand-by mode, supply current can be dramatically cut. Since the input-output voltage differential is small, loss control efficiency is good. The XC62E is particularly suited for use with battery operated portable products, and products where supply current regulation is required. The series comes in an ultra small SOT-25 package. In connection with the CE function, apart from the negative logic XC62EP series, a positive logic XC62ER series (custom) is also available. s Features Ultra small input-output voltage differential: 100mA of output current is available with a differential of 0.1V. (Performance depends on the external transistor characteristics.) Maximum output current: 1000mA Output voltage: 2V to 6V in 0.1V increments Highly accurate: Set-up voltage 2% Low power consumption: Typ.50A (VOUT=5.0V) Typ.0.2A (Stand-by) Output voltage temperature coefficient: Typ.100ppm/: Input stability: Typ.0.1%/V Ultra small package: SOT-25 mini-mold s Pin Configuration CE/CE EXT s Pin Assignment PIN NUMBER 1 2 3 4 5 PIN NAME VSS VIN VOUT EXT CE/CE FUNCTION Ground Supply voltage input Regulated voltage output Base current control Chip enable 5 4 1 VSS 2 VIN 3 VOUT SOT-25 (TOP VIEW) s Block Diagram VDD VOUT s Function SERIES XC62ER XC62EP CE H L H L OUTPUT VOLTAGE ON OFF OFF ON H=High Level L=Low Level EXT Current Limit CE Voltage Reference VSS s Standard Circuit PNPTr RBE RB EXT VOUT + VIN + CIN VIN CL RL CE VSS Peripherals : PNP Tr : 2SA1213 RBE : 20k ~ 47k RB : Please refer to Note 2 on the following page. CIN : 10F (Tantalum) CL : 47F (Tantalum) 10F minimum w s Functional Description Output voltage (VOUT) can be fixed by revising the external transistor's base current. This can be done by comparing the detected voltage level and the set voltage power supply level. With the XC62EP (CE negative voltage), if a voltage above the CE pin's "H" level is applied, the IC will enter stand-by mode where the base and differential amplifier's currents are regulated. s Suggestions for External Components 1. PNP Transistor The selection of a transistor should take into account output current, input voltage and power dissipation for each specific application. It is recommended that a transistor that has a low output saturated voltage (VCE) and high hFE characteristics be used. 2. RB Resistor Although the IC unit is protected by a base current remitter circuit, it is recommended that a resistor (RB) be connected between the transistor's base and the IC's EXT pin to protect the transistor. Required output current can be calculated using the following equation although characteristic variations and conditions of use should be carefully checked before use. The following equation also indicates the conditions needed to obtain IOUT (max.) at VIN (min.). However, the larger the input current, the larger the output current (IOUT) that can be obtained. VIN(min.) - 1.2(V) RB 0.7(V) RBE IOUT(max.) hFE 3. RBE Resistor, CL Capacitor To prevent oscillation due to output load variation, use of a phase compensation capacitor CL is recommended. Please use a Tantalum capacitor of at least 10F. Please also use an RBE resistor of less than 47k. An RBE resistor of between 20k and 47k is recommended for less power consumption. 4. Input Impedance In order to control oscillation brought about as a result of impedance at the power supply line, connect a capacitor of 10F or more (Tantalum) between the external transistor's emitter and the ground pin. s Special Note 1. Protection Circuit The built-in protect circuit is to protect the IC only. Therefore to prevent output shorts and overshoot current through the transistor, use of a resistor RB or an overshoot current protection circuit is recommended. Care should also be taken with the transistor's power dissipation. s Absolute Maximum Ratings Ta=25: PARAMETER VIN Input Voltage VOUT Output Voltage CE/CE Input Voltage SYMBOL VIN VOUT VCE VEXT IEXT Pd Topr Tstg RATINGS 12 VSS-0.3~VIN+0.3 VSS-0.3~VIN+0.3 12 50 150 -30~+80 -40~+125 UNITS V V V V mA Mw : : w EXT Output Voltage EXT Output Current Continuous Total Power Dissipation Operating Ambient Temperature Storage Temperature s Electrical Characteristics XC62EP3002 VOUT(T)=3.0V(Note1) PARAMETER Output Voltage Maximum Output Current* Load Stability* Input-OutputVoltage Differential (Note3) Supply Current1 Supply Current2 Input Stability* Input Voltage Output Voltage Temperature Characteristics* EXT Output Voltage EXT Leak Current CE "High" Level Voltage CE "Low" Level Voltage CE "High" Level Current CE "Low" Level Current SYMBOL VOUT(E) (Note2) IOUT max.
