RN5RF Series

LDO with External Tr.

The RN5RF Series are CMOS-based LDO regulators with external power transistor. By using an external PNP transistor, a low

dropout voltage regulator ranging from several tens of mA to several hundreds mA can be configured. (Use a low saturation type PNP

transistor with h^FEof approximately 100 to 300.)

FEATURES

• Supply Current (ISS) ························Typ. 30μA (VIN=SET VOUT+1V)

• Standby Current (Istandby) ·················Typ. 0.1μA (VIN=10V, In standby)

• Dropout Voltage (VDIF) ····················Typ. 0.1V ^∗(IOUT=100mA, VOUT=2.8V)

• Output Voltage Accuracy················ ± 2%

• Temp. coeff. of Output Voltage······· Typ. ± 100ppm/°C

• Line Regulation ······························ Typ. 0.05%/V

• Fold-back Protection Circuit··········· Current limit Typ. 8mA

• Ripple Rejection (RR)·····················Typ. 60dB ^∗(f=1kHz, VOUT 1.6V)

∗

Typ. 50dB (f=1kHz, VOUT 1.5V)

(Base current limit of PNP Tr.)

• Input Voltage Range (VIN)···············1.8V to 10.0V

• Output Voltage Range (VOUT)··········1.2V to 6.0V (internally fixed)

• Package ········································· SOT-23-5

) The value depends on the capacity of the external PNP transistor.
