DESCRIPTION
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 C_NR) is ideal
for powering VCOs. These devices are protected by
thermal shutdown and foldback current limit.
