Low drop-out, low output noise and high-speed load transient response achieved in an ultra-small package

TOKYO — (BUSINESS WIRE) — January 28, 2013 — Toshiba Corporation (TOKYO:6502) has expanded its line-up of 200mA single output CMOS-LDO regulators for mobile devices with low drop-out, low output noise and high-speed load transient response characteristics.

By using the latest generation micro-CMOS process, the new lineup, the TCR2EN, TCR2EE and TCR2EF series, achieves high performance characteristics required in analog circuits in an ultra-small package. In addition to the ultra-small 0.8 x 0.8 x 0.38mm package (SDFN4), the new lineup includes the ESV (SOT-553: 1.6 x 1.6 x 0.55mm) and SMV (SOT-25: 2.9 x 2.8 x 1.1 mm) general-purpose packages. The device line-up covers a range of voltage-clamp type output voltages, from 1.0V to 5.0V.

The new CMOS-LDO regulators are suitable for use in a wide range of mobile devices, such as smartphones, mobile phones, tablets, portable audio players, notebook PCs, digital camera and digital video cameras.

Applications

Mobile devices such as smartphones, mobile phones, tablets, portable audio players, notebook PCs, digital camera and digital video cameras.

Key Features

1. Low drop-out voltage
   V_IN-V_OUT = 160mV(typ.) at 2.5V output, I_OUT = 150mA (TCR2EN series)
   V_IN-V_OUT = 210mV(typ.) at 1.8V output, I_OUT = 150mA (TCR2EN series)
2. Low output noise voltage
   V_NO = 35μVrms(typ.) at 2.5V output, I_OUT = 10mA, 10 Hz < f < 100kHz
3. Excellent load transient response characteristics
   ΔV_OUT = ±55mV(typ.) at I_OUT = 1 ⇔ 150mA, C_OUT =1.0μF (TCR2EN series)
4. Wide output voltage range: V_OUT = 1.0 to 5.0V (voltage-clamp in increments of 50mV)
5. Low bias current ( I_B =35μA (typ.) at I_OUT =0mA)
6. High ripple compression: R.R = 73dB (typ.) at 2.5V output, I_OUT = 10mA, f = 1kHz
7. High output voltage accuracy: ±1.0% (1.8V ≤ V_OUT )
8. Built-in output auto-discharge function and pull-down control terminal connection
9. Small ceramic capacitors can be used. (C_IN = 0.1μF, C_OUT = 1.0μF )
