单路LDO.输入2-5.5V.输出3.3V.电流300mA.Iq 35uA.FP6146

General Description
The TK8210 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 TK8210
series is ideal for today's cutting edge
mobile phone. Intermnally the TK8210 includes a
reference voltage source, error amplifiers, driver
transistors, current limiters and phase
compensators.
The output voltage is set by current trimming.
Voltages are selectable in 100mV steps within a
range of 1.2V to 5.0V.
When the CE input pin is low, the fast discharge
channel can pass，a built-in pull-down resistor

pulls the output voltage low. Fast discharge

function optional.
The TK8210 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 tumed
off,resultingin greatly reduced power consumption.
