XTP2021
Ultra-Low Power Consumption LDO
1μA, 300mA Low Dropout Voltage Linear Regulator
Features
General Description
⚫
The XTP2021 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
⚫
1μA, 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 100nA(typical) when the low level
enable signal is turned off.
1μA Ground Current at no Load
±2% Output Accuracy
300mA 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
⚫
XTP2021 only needs 1uF ceramic capacitor to
⚫
work normally. The XTP2021 integrated shortcircuit current limiting and thermal shutdown
protection. And has automatic discharge function,
can be disabled in the state of rapid discharge
Stable with Ceramic or Tantalum Capacitor
Current Limit Protection
