TCR3DF Series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR3DF Series

300 mA CMOS Low Drop-Out Regulator with inrush current protection circuit

The TCR3DF series are CMOS general-purpose single-output voltage regulators with

an on/off control input, featuring low dropout voltage, low output noise voltage and low

inrush current.

These voltage regulators are available in fixed output voltages between 1.0 V and 4.5

V and capable of driving up to 300 mA.

They feature over-current protection, over-temperature protection, Inrush current

protection circuit and Auto-discharge function.

The TCR3DF series has a low dropout voltage of 230 mV (2.5 V output, I

= 300

OUT

mA) with low output noise voltage of 38 V

(2.5 V output) and a load transient

rms

response of only ⊿V

= ±85 mV ( I

= 1 mA⇔300 mA, C

=1.0 F).

OUT

SMV

Thus, the TCR3DF series are suitable for sensitive power supply such as Analog

and RF applications.

Weight:

SMV (SOT-25) (SC-74A) : 16 mg (Typ.)

Features

•

Low Drop-Out voltage

V_IN-V_OUT= 230 mV (typ.) at 2.5 V-output, I_OUT= 300 mA

V_IN-V_OUT= 290 mV (typ.) at 1.8 V-output, I_OUT= 300 mA

V_IN-V_OUT= 510 mV (typ.) at 1.2 V-output, I_OUT= 300 mA

Low output noise voltage

•

V_NO= 38 V_rms(typ.) at 2.5 V-output, I_OUT= 10 mA, 10 Hz ≤ f ≤ 100 kHz

•

Fast load transient response (⊿V_OUT= ±85 mV (typ.) at I_OUT= 1 ⇔ 300 mA, C_OUT=1.0 F )

High ripple rejection ( R.R = 70 dB (typ.) at 2.5 V-output, I_OUT= 10 mA, f = 1kHz )

Over-current protection

Over-temperature protection

Inrush current protection circuit

Auto-discharge function

Pull down connection between CONTROL and GND

Ceramic capacitors can be used ( C_IN= 1.0 F, C_OUT= 1.0 F )

General purpose package SMV(SOT-25) (SC-74A)
