FAST-TRANSIENT-RESPONSE 2-A LOW-DROPOUT VOLTAGE REGULATORS
FEATURES DESCRIPTION 1 2-A Low-Dropout Voltage Regulator Available in 1.5 V, 1.8 V, 2.5 V, 3.3 V Fixed
Output and Adjustable Versions Open Drain Power-On Reset With 100ms Delay
(TPS752xxQ) Open Drain Power-Good (PG) Status Output
(TPS754xxQ) Dropout Voltage Typically 210 mV at 2 A
(TPS75233Q) Ultralow 75-ОјA Typical Quiescent Current Fast Transient Response 2% Tolerance Over Specified Conditions for
Fixed-Output Versions 20-Pin TSSOP PowerPADв„ў (PWP) Package Thermal Shutdown Protection The TPS752xxQ and TPS754xxQ devices are
low-dropout regulators with integrated power-on reset
and power-good (PG) functions respectively. These
devices are capable of supplying 2 A of output
current with a dropout of 210 mV (TPS75233Q,
TPS75433Q). Quiescent current is 75 ОјA at full load
and drops down to 1 ОјA when the device is disabled.
These devices are designed to have fast transient
response for larger load current changes. 23 Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically
210 mV at an output current of 2 A for the
TPS75x33Q) and is directly proportional to the output
current. Additionally, because the PMOS pass
element is a voltage-driven device, the quiescent …
