SGM2025
Quad, Low Power, Low Dropout,
200mA, RF-Linear Regulators
GENERAL DESCRIPTION
The SGM2025 is a quad, low-power, low-dropout, CMOS
linear voltage regulator that operates from 3.3V to 5.5V
input and delivers up to 200mA continuous current at
each channel. An ultra low ground current (340μA at 0mA
output current) makes this part attractive for battery
operated power systems.
The SGM2025 also offers low dropout voltage (220mV at
200mA output) to prolong battery life in portable
electronics. Systems requiring a quiet voltage source,
such as RF applications, will benefit from the SGM2025
series’ ultra low output noise (30µV_RMS) and high PSRR.
An external noise bypass capacitor connected to the
device’s BP pin can further reduce the noise level.
Other features include a 10nA logic-controlled shutdown
mode, output current limit and thermal shut-down
protection.
SGM2025 is available in Green TQFN-3×3-16L package.
It operates over an ambient temperature range of -40℃
to +85℃.
