HT72Dxxxx

High PSRR 300mA Dual LDO Regulator

Features

General Description

Output Current: 300mA/Each Channel

The HT72Dxxxx series are CMOS-based voltage

regulator ICs with high output voltage accuracy, The

devices possess the benefits of dual outputs, low

output noise, high ripple rejection ratio, low dropout

and very fast turn-on times.

●

Dropout Voltage: 0.34V (Typ.)

(V_OUT=2.5V@I_OUT=300mA)

●

Maximum Input Voltage: 7.0V

●

Output Voltage Range: 1.5~5.0V

The devices include a reference voltage sources, error

amplifiers, driver transistors, current limiters and

phase compensators, all fully integrated.

High Output Voltage Accuracy: ±2%

Low Power Consumption: 30μA (typ.)

High Ripple Rejection: 70dB (1kHz@I_OUT=30mA)

Operating Temperature: -40°C~85°C

The HT72Dxxxx’s current limiters' fold back circuit

also operates as a short circuit protect function for

the output current limiter. This high level of output

stability is maintained even during frequent load

fluctuations, due to the excellent transient response

performance and high PSRR achieved across a broad

range of frequencies. The output voltage for each of

the dual internal regulators is fully independent. The

device has independent enable pins to shutdown each

internal regulator, resulting in greatly reduced power

consumption.

Low ESR Capacitor Compatible: Ceramic

Capacitor

equipment

●

Portable games

●

Camera, Video recorders

Portable audio equipment
