Low Power, Low Dropout,

SGM2014

250mA, RF - Linear Regulators

GENERAL DESCRIPTION

The SGM2014 series low-power, low-noise, low-dropout,

CMOS linear voltage regulators operate from a 2.5V to

5.5V input and deliver up to 250mA. They are the

perfect choice for low voltage, low power applications.

An ultra low ground current（160µA at 250mA output )

makes these part attractive for battery operated power

systems. The SGM2014 series also offer ultra low

dropout voltage (250mV at 250mA output) to prolong

battery life in portable electronics. Systems requiring a

quiet voltage source, such as RF applications, will

benefit from the SGM2014 series’ ultra low output noise

(30µVRMS) and high PSRR. An external noise bypass

capacitor connected to the device’s BP pin can further

reduce the noise level.

The output voltage is preset to voltages in the range of

1.5V

to

3.3V.

Other

features

include

a

10nA

logic-controlled shutdown mode, output current limit

and thermal shut- down protection.

Devices come in 5-pin SOT23 package.
