• 1.5-A Low-Dropout Voltage Regulator
The
TPS753xxQ
and
TPS751xxQ
devices
are
low-dropout regulators with integrated power-on reset
• Available in 1.5 V, 1.8 V, 2.5 V, and 3.3 V Fixed
and power-good (PG) functions respectively. These
Output and Adjustable Versions
devices are capable of supplying 1.5 A of output
• Open Drain Power-Good (PG) Status Output
current with a dropout of 160 mV (TPS75133Q,
(TPS751xxQ)
TPS75333Q). Quiescent current is 75
μA at full load
• Open Drain Power-On Reset With 100ms Delay
and drops down to 1
μA when the device is disabled.
(TPS753xxQ)
These devices are designed to have fast transient
response for larger load current changes.
• Dropout Voltage Typically 160 mV at 1.5 A
(TPS75133Q)
Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically

160 mV at an output current of 1.5 A for the

• 2% Tolerance Over Specified Conditions for
current.
Additionally,
because

element is a voltage-driven device, the quiescent
current is very low and independent of output loading
• 20-Pin TSSOP PowerPAD™ (PWP) Package
(typically 75
μA over the full range of output current,
• Thermal Shutdown Protection
1 mA to 1.5 A). These two key specifications yield a
significant
