SBVS034A - SEPTEMBER 2003 - REVISED NOVEMBER 2003
Cap Free, NMOS, 150mA Low Dropout Regulator with Reverse Current Protection
FEATURES D No Output Capacitor Required for Stability D Ultra-Low Dropout Voltage: 30mV typ D Excellent Load Transient Response--with or
without Optional Output Capacitor
DESCRIPTION
The TPS731xx 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. The TPS731xx 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
ESD rating, CDM 500 V (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under the Electrical Characteristics is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
