TCR2DG series

Low Noise 200 mA CMOS Low Drop-Out Regulator in ultra small package

The TCR2DG series are CMOS general-purpose single-output

voltage regulators with an on/off control input, featuring low dropout

voltage, low quiescent bias current and fast load transient response.

These voltage regulators are available in fixed output voltages

between 1.2 V and 3.6 V and capable of driving up to 200 mA. They

feature overcurrent protection and thermal shut down function.

The TCR2DG series is offered in the ultra small package WCSP4

( 0.79 mm x 0.79 mm x 0.5 mm). It has a low dropout voltage of 75

mV ( 2.5 V output, I_OUT= 100 mA) with low output noise voltage of 18

μV

(2.5 V output) and a load transient response of only

WCSP4

rms

⊿V_OUT= ±65 mV ( I_OUT= 1 mA⇔150 mA, C_OUT=1.0 μF).

As small ceramic input and output capacitors can be used with the

Weight : 0.7 mg (typ.)

TCR2DG series, these devices are ideal for portable applications that require high-density board assembly such as

cellular phones.
