General Description
pulls the output voltage low. Fast discharge
function optional.
The ASPL8210 series are highly accurate, low noise,
CMOS LDO Voltage Regulators. Offering low output
noise, high ripple rejection ratio, low dropout and very
fast turn-on times, the ASPL8210 series is ideal for
today’s cutting edge mobile phone. Internally the
ASPL8210 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators.
The ASPL8210 series is also fully
compatible with low ESR ceramic
capacitors, reducing cost and improving
output stability. 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 CE function allows the
output of regulator to be turned off,
resulting in greatly reduced power
consumption.
The output voltage is set by current trimming. Voltages
are selectable in 100mV steps within a range of 1.2V to
3.3V.
When the CE input pin is low, the fast discharge
channel can pass,a built-in pull-down resisto
