LDO Regulators :Single Output CMOS Type

CMOS LDO regulators are now available in the WCSP4 ultra-small package
The WCSP4 package occupies only 0.63 mm² of board area and is thus ideal for applications that require high-density board assembly. The CMOS LDO regulators in the WCSP4 package are available with a fixed output voltage between 1.2 V and 3.6 V. The output voltage is able to fix in steps of 50 mV. The TCR4SxxDWBG Series provides an auto-discharge function, which makes it ideal for applications with complex timing control.

WCSP4

Applications and Features

Applications

Cell phones, digital still cameras, portable audio players and other compact portable equipment

Features

High ripple rejection: R.R = 80 dB(typ.) at I_OUT = 10 mA,
f = 1 kHz
Low noise voltage: V_NO = 30 µVrms (typ.) at 2.5-V output,
I_out = 10 mA, 10 Hz ≤ f ≤ 100 kHz
Over current protection
Auto-Discharge Function (TCR4SxxDWBG)
Pull-down connection internally at the CONTROL pin (TCR4SxxDWBG)
Allows the use of ceramic capacitors: C_IN = 0.1 µF, C_OUT = 1.0 µF
Ultra-small package: WCSP4（0.79 × 0.79 × 0.50 mm）
