MIC5254
Dual 150mA μCap LDO
with Error Flag Outputs
General Description
Features
The MIC5254 is an efficient, precise, dual CMOS voltage
regulator. It offers better than 1% initial accuracy,
extremely low dropout voltage (typically 135mV at 150mA)
and low ground current (typically 90μA) over load. The
MIC5254 features two independent LDOs with error flags
that indicate an output fault condition such as overcurrent,
thermal shut-down and dropout.
Designed specifically for handheld and battery-powered
devices, the MIC5254 provides a TTL-logic-compatible
enable pin. When disabled, power consumption drops
nearly to zero.
The MIC5254 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in handheld wireless
devices.
Key features include current limit, thermal shutdown, faster
