SBVS037I – AUGUST 2003 – REVISED MAY 2006
Cap-Free, NMOS, 250mA Low Dropout Regulator
with Reverse Current Protection
Stable with No Output Capacitor or Any Value
The TPS732xx family of low-dropout (LDO) voltage
or Type of Capacitor
regulators uses a new topology: an NMOS pass
element in a voltage-follower configuration. This
Input Voltage Range: 1.7V to 5.5V
topology is stable using output capacitors with low
Ultralow Dropout Voltage: 40mV Typ at
ESR, and even allows operation without a capacitor.
250mA
It also provides high reverse blockage (low reverse
Excellent Load Transient Response—with or
current) and ground pin current that is nearly
without Optional Output Capacitor
constant over all values of output current.
New NMOS Topology Provides Low Reverse
The TPS732xx uses an advanced BiCMOS process
Leakage Current
to yield high precision while delivering very low
dropout voltages and low ground pin current. Current
Low Noise: 30
µV
RMS Typ (10kHz to 100kHz)
consumption, when not enabled, is under 1
µA and
0.5% Initial Accuracy
ideal for portable applications. The extremely low
1% Overall Accuracy (Line, Load, and
output noise (30
µV
RMS with 0.1µF CNR) is ideal for
Temperature)
powering VCOs. These devices are protected by
thermal shutdown and foldback current limit.
