150mA, Low-Dropout Linear Regulator
with Power-OK Output
General Description
The MAX8875 low-dropout linear regulator operates from
a +2.5V to +6.5V input range and delivers up to 150mA.
A P-channel MOSFET pass transistor allows its 85µA sup-
ply current to remain independent of the load, making this
device ideal for battery-operated portable equipment
such as PCS phones, cellular phones, cordless phones,
and modems.
The MAX8875 features a power-OK (POK) output that indi-
cates when the output is out of regulation. The device is
available in several preset output voltage versions: 5.0V,
3.3V, 3.0V, 2.7V, 2.5V, or 1.5V. Other features include 1µA
(max) shutdown current, short-circuit protection, thermal
shutdown protection, and reverse-battery protection. The
device comes in a miniature 5-pin SOT23 package.
The MAX8875 is optimized for use with a 1µF ceramic out-
put capacitor. For a pin-compatible, functionally equivalent
device for use with a higher ESR output capacitor, see the
MAX8885 data sheet.

The internal resistance of the STM32RTC power supply pin to ground is 3K?
I found that the mass-produced products always lost the clock, and the result was that the battery was dead. Then I measured the resistance of the RTC power supply pin to ground in the off state, and ...
