SGM2027
Dual, Low Dropout,
250mA LDO Regulator
GENERAL DESCRIPTION
The SGM2027 is a dual, low-power, low-dropout, CMOS
linear voltage regulator. It operates from a 2.5V to 5.5V
input voltage and delivers up to 250mA at each channel.
The SGM2027 is the perfect choice for low voltage, low
power. The ground current is 190μA (both LDO’s enabled
and active) that makes this part attractive for battery
operated power systems. The SGM2027 also offers low
dropout voltage (250mV at 250mA output) to prolong
battery life in portable electronics.
FEATURES
Highly Accurate: ±2%
Ultra-Low Dropout Voltage:
250mV at 250mA Output
190µA No-Load Supply Current
Thermal-Overload Protection
Output Current Limit
10nA Logic-Controlled Shutdown
Operating Temperature Range: -40℃ to +85℃
Available in Green TSOT-23-6 Package
Separate enable pins control each individual LDO output.
The EN function allows the output of each regulator to be
turned off independently, resulting in greatly reduced
power consumption. Other features include a 10nA
logic-controlled shutdown mode, current limit and thermal
shutdown protection.
The SGM2027 is available in Green TSOT-23-6 package.
It operates over an ambient temperature range of -40℃
to +85℃.

NOTES:
1. 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)
2. Time needed for VOUT to reach 95% of final value.
3. Each channel provides 300mA of maximum output current when the condition of dissipating heat is good.
