General Description
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.
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.
This family of low-noise regulators is available in 2mm x
?
all have an operating junction temperature range of ? 40 ° C
to + 125 ° C.

? 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
? Low ground current
? High PSRR: >60dB, up to 1kHz
? Output auto-discharge circuit (MIC37120/MIC37122)
? Thermal-shutdown and current-limit protection
Applications
? Mobile phones and consumer multimedia devices
