LDO Regulator TCR3UG Series Application for Power Supply of IoT Devices
This reference design provides document with low consumption current, PSRR, and dynamic response.The LDO has small package, low consumed power, and fast load transient response.
Ultra small package WCSP4F (0.645 mm x 0.645 mm (typ.), t: 0.33 mm (max))
Low quiescent bias current IB = 0.34 μA (up to 1.5V Output products, typ.) @IOUT = 0 mA
Wide range output voltage (VOUT = 0.8 V to 5.0 V)
High ripple rejection ratio 70 dB (0.8V Output product, typ.)@1 kHz
Low dropout voltage VDO = VIN - VOUT = 155 mV (3.3V Output product, typ.) @IOUT = 300 mA
Overcurrent protection function
Thermal shutdown function
Built-in auto-discharge function (TCR3UGxxA series) / Not-built-in auto-discharge function (TCR3UGxxB series)
Inrush current reduction function ( output voltage soft start )
The TCR3UG series have compatibility with low consamption current (low quiscent current and low stand-by current) and fast load transient response, qnd these devices are ideal for battery drive IoT devices that require low power consumption.
This voltage regulators have 31 output voltage linups from 0.8 V to 5.0 V.
As small ceramic input and output capacitors can be used with the TCR3UG series.
