3 Description
The TPS732-Q1 family of low-dropout (LDO) 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 TPS732-Q1 family of devices uses an advanced
BiCMOS process to yield high precision while
delivering 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.
