SGM2023
Quad, Low Power, Low Dropout,
200mA, RF-Linear Regulators
GENERAL DESCRIPTION
The SGM2023 is a quad, low-power, low-dropout, CMOS
linear voltage regulator that operates from 2.5V to 5.5V
input and delivers up to 200mA continuous current at
each channel. An ultra low ground current (350μA at 0mA
output current) makes this part attractive for battery
operated power systems.
The SGM2023 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 SGM2023
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.
Other features include a 10nA logic-controlled shutdown
mode, output current limit and thermal shut-down
protection.
SGM2023 is available in Green TQFN-3×3-16L package.
It operates over an ambient temperature range of -40℃
to +85℃.

NOTES:
1. VIN = VOUT(NOMINAL) + 0.5V or 2.5V, whichever is greater.
2. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V. (Only applicable
for VOUT = +2.5V to +3.3V.)
3. Time needed for VOUT to reach 95% of final value.
