Medium-Current, Noise-Sensitive
Applications
The RS3236 series low-power, low-dropout, CMOS
LDO operate from 1.7V to 7.5V input voltage that
can supply up to 500mA of output current. Designed
to meet the requirements of RF and analog circuits,
the RS3236 series device provides low noise, high
PSRR, low quiescent current, and low line and load
transient response.
The device is designed to work with a 1-µF input
and a 1-µF output ceramic capacitor (no separate
noise bypass capacitor required). 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, foldback current limit and thermal
shutdown protection.
The RS3236 series is available in Green UTDFN1x1-4, SOT23-3, SOT23-5, SOT353(SC70-5) and
SOT89-3L(L-Type) package. It operates over an
ambient temperature range of -40°C to +85°C.

NOTES:
1. VIN = VOUT (NOMINAL) + 0.5V or 1.7V, 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.
3. Time needed for VOUT to reach 90% of final value.
