Part Number : TPS73618-Q1
Function : Automotive Catalog, Single Output LDO, 400mA, Fixed (1.8V), Cap free, Low Noise
Manufacturers : Texas Instruments
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.
