General Description

The HT75Bxx series are CMOS-based voltage

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.

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.

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

an attractive additional feature for pocket and hand-

held applications.
