3 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.
It 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.
