HT75Bxx

High PSRR 150mA LDO Regulator

Features

General Description

Output Voltage:

The HT75Bxx series are CMOS-based voltage

●

1.5V/1.8V/2.5V/2.8V/3.0V/3.3V/5V

regulator devices with high output voltage accuracy,

low quiescent current, low on-resistance, and high

ripple rejection. Each of the devices includes a voltage

reference, error ampliﬁer, resistor-network for voltage

setting, current limit circuit, chip enable circuit and so

on.

High Output Voltage Accuracy: ±2%

●

Low Voltage Drop: 330mV(Typ.)

(V_OUT=2.5V@I_OUT=150mA)

Maximum Input Voltage: 7.0V

Guaranteed Output Current: 150mA

Low Power Consumption: 10μA (Typ.)

High ripple rejection: 70dB (1kHz@I_OUT=30mA)

Power-Saving Shutdown Mode

Current limiting

●

The HT75Bxx’s current limiters' fold back circuit

also operates as a short circuit protect function for the

output current limiter.

These devices offer the benefits of low dropout

voltage as well as possessing a chip-enable function.

Additional features include an exceptionally low

10μA quiescent current in addition to excellent line

and load transient response characteristics. With these

features the devices will be appropriate for use in a

wide range of application among which would include

hand-held communication equipment.

SOT23-5 and SOT89 Package

Applications

Portable communication equipment

●

Portable music player

Electrical appliances such as cameras,

VCRs and camcorders

The space-saving SOT23-5, SOT89 package will be

an attractive additional feature for pocket and hand-

held applications.

Battery-powered equipment
