200-mA CMOS LDO Regulators in a Ultra-Small Package (Single-Output)
TCR4SxxWBG and TCR4SxxDWBG Series
New Product
CMOS LDO regulators are now available in the WCSP4 ultra-small package
The WCSP4 package occupies only 0.63 mm 2 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.
■ Applications
Cell phones, digital still cameras, portable audio players and other
compact portable equipment
■ Features
● High ripple rejection: R.R = 80 dB (typ.) at IOUT = 10 mA, f = 1 kHz
● Low noise voltage: VNO = 30 μVrms (typ.) at 2.5-V output,
IOUT = 10 mA, 10 Hz ≤ f ≤ 100 kHz
● Allows the use of ceramic capacitors (CIN = 0.1 μF, COUT = 1.0 μF)
● Ultra-small package: WCSP4 (0.79 x 0.79 x 0.50 mm)

Digital-Output Magnetic Sensors
TCS20DPC, TCS20DLC
Available in the 0.38-mm ultra-thin, small CST6C package
The TCS20DPC and TCS20DLC are digital-output magnetic sensors. These digital-output magnetic sensors are ideal for applications
with open/close or sliding mechanisms, such as cell phones, notebook PCs and digital still cameras. The new digital-output magnetic
sensors are much thinner and smaller than their predecessors and thus save board space.
■ Applications
Cell phones, notebook PCs, digital still cameras, etc.
■ Features
● Ultra-thin, small package with a thickness of 0.38 mm
(CST6C: 1.5 mm x 1.15 mm x 0.38 mm)
● South-Pole and North-Pole detections (Double detections)
● Magnetic flux density (|BON| = 3.8 mT (max), |BOFF| = 0.3 mT (min))
● Push-pull output (TCS20DPC) and open-drain output (TCS20DLC)
● Low quiescent-bias current (Average current ICC = 12.8 μA at VCC =
3.3 V)
● Extended operating voltage range (VCC = 2.3 to 3.6 V)
