HOLTEK HT75B33

HT75Bxx
High PSRR 150mA LDO Regulator
Features
General Description
●● Output Voltage:
1.5V/1.8V/2.5V/2.8V/3.0V/3.3V/5V
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.
●● High Output Voltage Accuracy: ±2%
●● Low Voltage Drop: 330mV(Typ.)
(VOUT=2.5V@IOUT=150mA)
●● Maximum Input Voltage: 7.0V
●● Guaranteed Output Current: 150mA
●● Low Power Consumption: 10μA (Typ.)
●● High ripple rejection: 70dB (1kHz@IOUT=30mA)
The HT75Bxx’s current limiters' fold back circuit
also operates as a short circuit protect function for the
output current limiter.
●● Power-Saving Shutdown Mode
●● Current limiting
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 handheld applications.
●● Battery-powered 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. 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.
4. Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a
specified output current. Under dropout conditions, the output voltage will be equal to: VIN – VDROP.
