General Description
The HT72Dxxxx series are CMOS-based voltage
regulator ICs with high output voltage accuracy, The
devices possess the benefits of dual outputs, low
output noise, high ripple rejection ratio, low dropout
and very fast turn-on times.
The devices include a reference voltage sources, error
amplifiers, driver transistors, current limiters and
phase compensators, all fully integrated.
The HT72Dxxxx’s current limiters' fold back circuit
also operates as a short circuit protect function for
the output current limiter. This high level of output
stability is maintained even during frequent load
fluctuations, due to the excellent transient response
performance and high PSRR achieved across a broad
range of frequencies. The output voltage for each of
the dual internal regulators is fully independent. The
device has independent enable pins to shutdown each
internal regulator, resulting in greatly reduced power
consumption.
