LOW RIPPLE VOLTAGE REGULATOR WITH EXTERNAL TRANSISTOR
| The RN5RF Series are voltage regulator ICs which control external driver transistors
with high ripple rejection, high accuracy output voltage, low supply current by CMOS process. Each of these
voltage regulator ICs consists of a voltage reference unit, an error amplifier, output voltage setting resistor,
short circuit current limiting circuit and chip enable circuit. These ICs are suitable for constructing regulators
with ultra low dropout voltage and an output current in the range of several tens of mA and several hundreds
mA. In addition to low supply current by CMOS process, chip enable function can be used to conserve battery
life during standby. Furthermore, a supreme ripple rejection and a transient response are suited for portable
communicatior such as cell phones, PDAs, walky talkies.SOT-23-5 (Mini-mold) package is available. |
