RT9010
300mA LDO Regulator with POR
General Description
Features
z Wide Operating Voltage Ranges : 2.5V to 5.5V
RT9010 is a low noise, and low dropout with the sourcing
ability up to 300mAand power-on reset function. The range
of output voltage is from 1.2V to 3.6V by operating from
2.5V to 5.5V input.
z Low-Noise for RF Application
z No Noise Bypass Capacitor Required
z Fast Response in Line/Load Transient
z TTL-Logic-Controlled Shutdown Input
z Low Temperature Coefficient
z 300mA LDO Outputs
RT9010 offers 2% accuracy, extremely low dropout voltage
(240mV @ 300mA), and extremely low ground current.
The shutdown current is near zero current which is suitable
for battery-power devices. Other features include current
limiting, over temperature, output short circuit protection.
z High Accuracy 2%
z Short Circuit Protection
z Thermal Shutdown Protection
z Current Limit Protection
RT9010 is short circuit thermal folded back protected.
RT9010 lowers its OTP trip point from 165°C to 110°C
when output short circuit occurs (VOUT < 0.4V) providing
maximum safety to end users.
z Short Circuit Thermal Folded Back Protection
z Tiny TSOT-23-6 Package
z RoHS Compliant and 100% Lead (Pb)-Free
RT9010 can operate stably with very small ceramic output
capacitors, reducing required board space and component
cost. RT9010 is available in fixed output voltages in the
TSOT-23-6 package.
Applications
z CDMA/GSM Cellular Handsets
z Battery-Powered Equipment
z Laptop, Palmtops, Notebook Computers
z Hand-Held Instruments
