Manufacturer: Texas Instruments


TPS73618-Q1 datasheet



The TPS736xx-Q1 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.

The topology also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current. The TPS736xx-Q1 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 1 μA and ideal for portable applications. The extremely low output noise (30 μV RMS with 0.1 μF Cnr ) is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit.


1. Input Voltage Range of 1.7 to 5.5 V

2. Ultra-Low Dropout Voltage: 75 mV typ

3. New NMOS Topology Delivers Low Reverse-Leakage Current
