CMOS 3CH-LDOs for RF Unit R5324D SERIES NO. EA-099-0301 OUTLINE The R5324D Series are CMOS-based multi positive voltage regulator ICs with high output voltage accuracy, low supply current, low noise, low dropout and high ripple rejection. The R5324D Series contain three voltage regulators. Each of these voltage regulators in the R5324D Series consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on. The chip enable function contributes to prolong battery life. Further, regulators in the R5324D Series are with low dropout voltage, excellent load transient response and line transient response, thus the R5324D series are very suitable for the power supply for hand-held communication equipment. Since the package for these ICs is SON-8, high density mounting of the ICs on boards is possible.

this IC, ESR of the output capacitors should be set in the range of the following graphs. Noise level is measured with a spectrum analyzer and hatched area shows stable areas of which noise level is approximately equal or less than 40V (Avg.). The relation between Load Current (IOUT) and Equivalent Series Resistors (ESR) value of external output capacitor with the stable area is shown below; 1.5V(VR1) 100 100 Output Current IOUT3(mA) 1.5V(VR2) 10 10 ESR () 1 ESR () 0 50 100 150 200 1 0.1 0.1 0.01 0.01 0 50 100 150 Output Current IOUT(mA) Output Current IOUT(mA) 27 R5324D 1.5V(VR3) 100 100 2.8V(VR1) 10 10 ESR () 1 ESR () 0 20 40 60 80 100 1 0.1 0.1 0.01 0.01 0 50 100 150 200 Output Current IOUT(mA) Output Current IOUT(mA) 2.8V(VR2) 100 100 2.8V(VR3) 10 10 ESR () 1 ESR () 0 50 100 150 1 0.1 0.1 0.01 0.01 0 20 40 60 80 100 Output Current IOUT(mA) Output Current IOUT(mA) Measuring Conditions Frequency Band : 10Hz to 2MHz Temperature : -40C to 85C 28 |
