Description
Quad, Low Power, Low Dropout, 200ma, Rf-linear Regulators
Manufacturer

Datasheet
GENERAL DESCRIPTION
The SGM2024 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 SGM2024 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 SGM2024
series’ ultra low output noise (30µV
An external noise bypass capacitor connected to the
device’s BP pin can further reduce the noise level.
Other features include a10nA logic-controlled shutdown
mode, output current limit and thermal shut-down
protection.
SGM2024 is available in Pb-free TQFN-16 (3mm×3mm)
package. It operates over an ambient temperature range
of -40°C to +85°C.
