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 Tiny 8-pin 2mm x 2mm Thin MLF package respond to any load change quickly even though it is a low Ultra-low dropout voltage 120mV 300mA quiescent current part. This combination of PSRR, low Low output voltage noise 50Vrms noise and transient response, along with low power Current-limit and thermal-shutdown protection consumption makes for a very-high performance, yet general purpose product. The MIC5332 is a Cap design, operating with very-small Applications ceramic output capacitors, which reduces required board Camera phones space and component cost. It is available in fixed output voltages in a tiny 8-pin 2mm x 2mm Thin MLF leadless Mobile phones package.

Pin Configuration 8-Pin 2mm x 2mm Thin MLF (MT) (Top View) 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. M9999-091212-B September 2012 2
