DESCRIPTION
The TPS736xx 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 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 1mA and
ideal for portable applications. The extremely low
output noise (30mV_RMS with 0.1mF C_NR) is ideal for
powering VCOs. These devices are protected by
thermal shutdown and foldback current limit.
