DESCRIPTION/ORDERING INFORMATION
This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital
switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails,
with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the VCCA supply, and the B
ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. This allows the support of
both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the
1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly
reduces the power-supply quiescent current consumption.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

TPS728xx Series 200mA Low-Dropout Linear Regulator with Pin-Selectable Dual-Voltage Level Output
TPS728xx Series
200mA Low-Dropout Linear Regulator
with Pin-Selectable Dual-Voltage Level Output
1FEATURES
APPLICATIONS
2• Very Low Dropout: 230mV Typical at 200mA
• 3% Accuracy Over Load/Line/Temperature
• Low I Q : 50 μ A in Active Mode
• Available in Fixed-Output Voltages From 0.9V
to 3.6V Using Innovative Factory EEPROM
Programming
• VSET Pin Toggles Output Voltage Between
Two Preset Levels
– Preset Output Voltage Levels Can Be
EEPROM-Programmed To Any Combination
• High PSRR: 65dB at 1kHz
• Stable with a 1.0 μ F Ceramic Capacitor
• Thermal Shutdown and Over-Current
Protection
• Available in Wafer-Level Chip Scale and
2mm x 2mm SON Packages
• Power Rails with Programming Mode
• Dual Voltage Levels for Power-Saving Mode
• Leakage Reduction for 90nm and 65nm
Processors
• Wireless Handsets, Smart Phones, PDAs
• MP3 Players and Other Handheld Products
DESCRIPTION
The TPS728xx series of low-dropout linear regulators
(LDOs), with a selectable dual-voltage level output, is
designed specially for applications that require two
levels of output voltage regulation. Programming
fuses and memory cards, reducing leakage effects,
and conserving power in nanometric processes are
some application examples.
The VSET pin is used to select one of two output
voltage levels preset through innovative factory
EEPROM programming. A precision bandgap and
error amplifier provides an overall 3% accuracy over
load, line, and temperature extremes.
Ultra-small wafer chip scale (WCSP) and 2mm x
2mm SON packages make the TPS728xx series ideal
for handheld applications.
This family of devices is fully specified over a
temperature range of T J = – 40 ° C to +125 ° C.
