| NJM723 PRECISION VOLTAGE REGULATOR GENERAL DESCRIPTION The NJM723 is a Precision Monolithic Voltage Regulator. The device consists of a temperature-compensated Voltage reference, error amplefier, power-series pass transistor and current-limit circuitry. Additional NPN or PNP pass elements may be used when output currents exceeding 150mA are required. In addition to the above, the device features low standby current drain, low temperature drift and high ripple rejection. The NJM723 is intended for use with positive or negative supplies as a series, shunt, switching of floating instrument power supplies, and other power supplies for digital and linear circuits. FEATURES * Operating Voltage (12V to 40V) * 150mA output current without external pass transistor * Output currents in excess of 10A posible by adding external * Input voltage 40V max * Output voltage adjustable from 2V to 37V * Can be used as elther a linear or a switching regulator. * Package Outline DIP14, DMP14, SSOP14 * Bipolar Technology PIN CONFIGURATION PACKAGE OUTLINE NJM723D NJM723M NJM723V NJM723D NJM723M NJM723V EQUIVALENT CIRCUIT Ver.2003-07-18 -1- NJM723 ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Drpout Voltage Differential Input Voltage Output Current Power Dissipation Current from VREF Operating Temperature Range Storage Temperature Range SYMBOL V /V + - (Ta=25C) RATINGS 40 40 5 150 (DIP8) 700 (DMP8) 700 (note) (SSOP8) 450 (note) 15 -20 to +75 -40 to +125 UNIT V V V mA mW mW mW mA C C VIO VIN (diff) IO PD IREF (VREF) Topr Tstg (note) At on PC board ELECTRICAL CHARACTERISTICS PARAMETER Line Regulation Load Regulation Ripple Rejection Average Temperature Coefficient of Output Voltage Short Circuit Current Limit Reference Voltage Output Noise Voltage Dropout Voltage Standby Current Drain Input Voltage Range Output Voltage Range SYMBOL VIO - VIN VO - VO RR (Ta=25C, V+=Vc=12V, V-=0V, V0=5V, RSC=0, CI=100pF, CREF=0, IL= 1mA) TEST CONDITION VIN = 12 to 15V VIN = 12 to 40V IO = 1 to 50mA f = 50 to 10kHz, CREF = 0 f = 50 to 10kHz, CREF = 5F MIN. 6.8 BW = 100Hz to 10kHz, CRF = 0 BW = 100Hz to 10kHz, CRF = 5F 3.0 IL = 0, VIN = 30V, VO = VREF 9.5 2.0 TYP. 0.01 0.1 0.03 74 86 0.003 65 7.15 100 2.5 2.3 MAX. 0.1 0.5 0.2 0.018 7.5 38 4.0 40 37 UNIT %VOUT %VOUT %VOUT dB dB %/C mA V Vrms Vrms V mA V V VO/T ICL VREF VNO VIO ISTDBY VIN VO -20 Ta 75 C RSC = 10, VOUT = 0 -2- Ver.2003-07-18 NJM723 TYPICAL APPLICATION Maximum Load Current vs. Input Output Voltage Differential Load Regulation vs. Output Current Relative Output Voltage vs. Output Current Standby Current vs. Input Voltage TYPICAL CHARACTERISTICS Ver.2003-07-18 -3- NJM723 [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
