TPS736xx  
www.ti.com  
SBVS038K–SEPTEMBER 2003–REVISED SEPTEMBER 2005  
Cap-Free, NMOS, 400mA Low-Dropout Regulator  
with Reverse Current Protection  
FEATURES  
DESCRIPTION  
•
Stable with No Output Capacitor or Any Value  
or Type of Capacitor  
The TPS736xx family of low-dropout (LDO) linear  
voltage regulators uses a new topology: an NMOS  
pass element in a voltage-follower configuration. This  
topology is stable using output capacitors with low  
ESR, and even allows operation without a capacitor.  
It also provides high reverse blockage (low reverse  
current) and ground pin current that is nearly constant  
over all values of output current.  
•
•
•
Input Voltage Range of 1.7V to 5.5V  
Ultra-Low Dropout Voltage: 75mV typ  
Excellent Load Transient Response—with or  
without Optional Output Capacitor  
•
New NMOS Topology Delivers Low Reverse  
Leakage Current  
The TPS736xx uses an advanced BiCMOS process  
to yield high precision while delivering very low  
dropout voltages and low ground pin current. Current  
consumption, when not enabled, is under 1µA and  
ideal for portable applications. The extremely low  
output noise (30µVRMS with 0.1µF CNR) is ideal for  
powering VCOs. These devices are protected by  
thermal shutdown and foldback current limit.  
•
•
•
Low Noise: 30µVRMS typ (10Hz to 100kHz)  
0.5% Initial Accuracy  
1% Overall Accuracy Over Line, Load, and  
Temperature  
•
•
Less Than 1µA max IQ in Shutdown Mode  
Thermal Shutdown and Specified Min/Max  
Current Limit Protection  
•
Available in Multiple Output Voltage Versions  
– Fixed Outputs of 1.20V to 4.3V  
– Adjustable Output from 1.20V to 5.5V  
– Custom Outputs Available
