AME8831 - Low-Quiescent LDO

General Description

The AME8831 family of positive, linear regulators feature low quiescent current (17µA typ.) with low dropout voltage, making them ideal for battery applications.

The space-saving SOT-25 package is attractive for “ Pocket ” and “ Hand Held” applications.

Key Features

  • a logic-enabled sleep mode to shutdown the regulator, reducing quiescent current to 1µA typical at TA= 25oC. The AME8831 is stable with an output capacitance of 4.7µF or larger. www. DataSheet4U. com 150mA Hi-PSRR, Low-Quiescent LDO with In-Rush Current Control For USB.

AME, Inc. AME8831 n General Description The AME8831 family of positive, linear regulators feature low quiescent current (17µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-25 package is attractive for “ Pocket ” and “ Hand Held” applications. These rugged devices have both Thermal Shutdown, and Current limitation to prevent device failure under the “ Worst” of operating conditions. In applications requires a low noise regulated supply. The AME8831 family uses the SR pin to program the output voltage’ s slew rate to control the in-rush current. This is specifically used in the USB application where large load capacitance is present at start-up.
