R1170x Series

800mA LDO

The R1170x Series are CMOS-based LDO regulators featuring 800mA output.

The CMOS process provides both high output current and low supply current. The dropout voltage is significantly lower than bipolar

regulators. The CE pin can switch the regulator into standby mode. In addition to a fold-back protection circuit built into conventional

LDO regulators, R1170x has a thermal shutdown circuit. Ceramic capacitors can be used.

FEATURES

• Supply Current (ISS) ····················Typ. 80μA (VIN=SET VOUT+1V)

• Standby Current (Istandby) ·············Typ. 0.1μA (VIN=6V, in standby)

• Dropout Voltage (VDIF) ················Typ. 0.12V (IOUT=300mA, VOUT=2.8V)

• Ripple Rejection (RR)·················Typ. 50dB (f=1kHz)

• Input Voltage Range (VIN)···········Max. 6.0V

• Output Voltage Range (VOUT)······1.5V to 5.0V (internally fixed)

• 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. 40mA

• Thermal Shutdown Circuit ··············Stops at 150°C

• Packages········································HSON-6, SOT-89-5, HSOP-6J

• Ceramic capacitors can be used. ···10μF or more
