XTP2038
15μA, 500mA Low Dropout Voltage Linear Regulator
Features
General Description
⚫
The XTP2038 is a ultra-low-power, low-step-
⚫
down linear regulator that supports a wide voltage
input of 1.8V to 5.5V and a standby current of
⚫
15μA, making these devices ideal for battery-
⚫
powered systems that spend most of their time in
⚫
standby mode, requiring minimal standby power
⚫
consumption to extend the life of the device.
⚫
Integrated enable control mode that reduces
current to only 10nA(typical) when the low level
enable signal is turned off.
15μA Ground Current at no Load
±2% Output Accuracy
500mA Output Current
10nA Shutdown Current
Input Voltage Range: 1.8V to 5.5V
Dropout Voltage: 0.18V at 300mA
Fixed Output Voltage
0.9V,1.05V,1.2V,1.5V,1.8V,1.9V,2.5V,2.7V,2.
8V,2.85V,2.9V,3.0V,3.3V,3.6V,4V and 5V
⚫
XTP2038 only needs 1uF ceramic capacitor to
⚫
work normally. The XTP2038 integrated shortcircuit current limiting and thermal shutdown
⚫
protection. And has automatic discharge function,
can be disabled in the state of rapid discharge
VOUT.
Adjustable Output from 0.8V to 5.0V
Stable with Ceramic or Tantalum Capacitor
