TCR3UG series
Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Drop-Out Regulator in ultra
small package
1. Description
The TCR3UG series are CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring ultra low
quiescent bias current and low dropout voltage.
These voltage regulators are available in fixed output voltages
between 0.8 V and 5.0 V and capable of driving up to 300 mA.
They feature Over-current protection, Thermal Shutdown function
and Auto-discharge option.
The TCR3UG series is offered in the ultra small plastic mold
package WCSP4F (0.645 mm x 0.645 mm; t 0.33 mm (max)) and
has a low dropout voltage of 155 mV (3.3 V output, I
OUT
= 300
mA). As small ceramic input and output capacitors 1μF can be used with the TCR3UG series, these devices
are ideal for portable applications that require high-density board assembly such as cellular phones.
