MIC5332
Micro-Power, High-Performance
Dual 300mA ULDO
General Description Features
The MIC5332 is a tiny, dual, low quiescent current LDO
2.3V to 5.5V input voltage range
ideal for applications that are power sensitive. The
300mA output current per LDO
MIC5332 integrates two high-performance 300mA LDOs,
Very-low quiescent current: 25A per LDO
and a power-on-reset (POR) generator into a 2mm x 2mm
POR output with programmable delay on LDO2
Thin MLF package. This solution occupies the same PC
board area of a single SOT-23 package. High PSRR - >65dB on each LDO
The MIC5332 is designed to reject input noise and provide Stable with 1F ceramic output capacitors
low output noise with fast transient response so as to

Pin Description
Pin Number Pin Name Pin Function
1 VIN Supply Input.
2 GND Ground.
3 POR2 Power-On Reset Output (Regulator 2): Open-drain output. Active low indicates an output under-
voltage condition on regulator 2 when the device is enabled.
4 EN2 Enable Input (Regulator 2): Active High Input. Logic High = On; Logic Low = Off. Do not leave
floating.
5 EN1 Enable Input (Regulator 1): Active High Input. Logic High = On; Logic Low = Off. Do not leave
floating.
6 CSET2 Delay Set Input (Regulator 2): Connect external capacitor to GND to set the internal delay for the
POR2 output. When left open, there is no delay. This pin cannot be grounded.
7 VOUT2 Regulator Output LDO2.
8 VOUT1 Regulator Output LDO1.
EP ePad .Exposed Heat Sink Pad. Connect to GND for best thermal performance.
