Holtek HT72D1833 High psrr 300ma dual ldo regulator Datasheet

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.)
(VOUT=2.5V@IOUT=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@IOUT=30mA)
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.
●● Operating Temperature: -40°C~85°C
●● Low ESR Capacitor Compatible: Ceramic
Capacitor
●● Over Temperature Protection
●● Current Limiting
●● Ultra Small Package: SOT23-6
Applications
●● Mobile phones
●● Cordless phones and radio communication
equipment
●● Portable games
●● Camera, Video recorders
●● Portable audio equipment

Note 1. Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating
Ratings indicate conditions for which the device is intended to be functional, but do not guarantee
specific performance limits. The guaranteed specifications apply only for the test conditions listed.
2. Specifications are production tested at TA=room temperature. Specifications over the -40°C to 85°C
operating temperature range are assured by design, characterization and correlation with Statistical
Quality Controls (SQC).
3. The input/output differential voltage multiplied by the output current must be less than than the package
power dissipation value of 250mW.
4. Load regulation is measured at constant junction temperature, using pulse testing with a short ON time.
The devices are guaranteed up to the maximum power dissipation. Power dissipation is determined by the
input/output differential voltage and the output current. Guaranteed maximum power dissipation will not
be available over the full input/output range. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(MAX) – TA)/θJA.
5. Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a
specified output current. During dropout conditions, the output voltage will be equal to: VIN – VDROP.
