6.6V, 250mA TinyPower^TMHigh PSRR LDO

with Protections

Features

General Description

• 2.3V to 6.6V operating input voltage

• Up to 250mA output current capability

The HT73Lxx are a series of low dropout voltage

regulators with an input voltage range from 2.3V to

6.6V. They are available in a range of fixed output

• Fixed output voltage range: 0.9V, 1.05V, 1.2V,

1.5V, 1.8V, 2.5V, 2.7V, 3.0V, 3.3V and 3.6V with

±2% accuracy

voltages from 0.9V to 3.6V. When the CE pin input is

low, a fast discharge path pulls the output voltage low

via an internal pull-down resistor. An internal over-

current protection circuit prevents the devices from

damage even if their output was shorted to ground. An

over-temperature protection circuit ensures the device

junction temperature will not exceed a temperature of

150ºC.

• Ultra low input consumption current: 1.35μA

(typical)

• Stable with 1µF ceramic output capacitor

• Fast output discharge to ground when shutdown

• Soft-start function when powered on

• High PSRR: 75dB at 1kHz

Due to the device’s outstanding PSRR and low output

noise performance features, they are suitable for

use in powering RF applications such as sub-1GHz

transceivers. Their ultra-small 4-pin DFN package

type with their 0.4mm thickness makes the devices

also suitable for space limited applications such as

ﬁnancial/credit cards or smart wearable products.

• Low output noise: 50µV_RMSfrom 10Hz to 100kHz

• Over current and over temperature protection features

• Enable/disable function

• Package types: 4-pin DFN, 5-pin SOT23 and

3-pin SOT89

Applications

• IoT devices

• Smart/Health wearable devices
