MIC37110/MIC37112

MIC37120/MIC37122

High-Performance, Low-Noise,

1A LDOs

General Description

Features

The MIC37110/MIC37112 and MIC37120/MIC37122 are

high-performance, low-noise, low dropout regulators. Each

of these LDOs is capable of sourcing 1A output current,

offers high power supply rejection, and low output noise.

These general purpose LDOs are most suitable for

consumer applications such as multimedia devices, set-top

boxes, Blu-ray players, handheld devices, and gaming

consoles.

• Input voltage range: 2.375V to 5.5V

• Output voltage adjustable down to 1.0V

(MIC37112/MIC37122)

• Stable with small, 2.2µF ceramic output capacitor

• 230mV typical dropout at 1A

• 1A minimum guaranteed output current

• ±2.0% initial accuracy

The MIC37112 and MIC37122 feature adjustable output

voltages while the MIC37110 and MIC37120 come in fixed

1.8V output voltage options. All devices feature 2% initial

output voltage accuracy, typical dropout of 230mV at 1A,

and low ground current.

• Low ground current

• High PSRR: >60dB, up to 1kHz

• Output auto-discharge circuit (MIC37120/MIC37122)

• Thermal-shutdown and current-limit protection

This family of low-noise regulators is available in 2mm x

2mm Thin MLF^®, SOIC-8 and SOT-223 packages and they

all have an operating junction temperature range of −40°C

to +125°C.
