1.5 A LDO regulators in industryʼs smallest package for mobile applications: TCR15AG series
Despite its small package, the TCR15AG series feature high output current of 1.5 A, suiting it for power supply applications in Wi-Fi® chipsets for smartphones and tablets, cameras and wireless modules.
The new series can also control power supply in applications requiring a high current, including laptop PCs, digital camcorders, storage devices and set-top boxes.
TCR15AG series deliver the industryʼs best-in-class ripple rejection ratio and load transient response. They significantly reduce the ripple noise from a power management IC (PMIC) or a DC-DC converter that is often a limiting factor in the power supply for cameras and RF circuits. They help to minimize output voltage fluctuations that occur in response to sharp changes in current during mode transitions in cameras and RF circuits.
Low voltage dropout is secured by use of an external bias voltage pin, which helps to improve system power efficiency and contributes to longer charge life for the batteries of mobile products.
The series offers two kinds of output voltage--adjustable output between 0.60 V and 3.6 V via external resistors, and fixed output voltages from 0.65 V to 3.6 V--enabling support for a wide range of power supply applications.
Extensive protection features of the TCR15AG series include overcurrent protection and thermal shutdown, positioning it as a high-efficiency LDO solution for applications requiring highly regulated voltage in the high-current region and low power consumption.

 Not including a control terminal current (ICT) and a current flowing through an external resistor for a variable-output LDO regulator.
 @VBIAS=3.3 V, VIN=VOUT+1 V, IOUT=10 mA, VOUT=0.9 V, f=1 kHz, VIN Ripple=200 mVp-p, Ta=25°C, COUT=4.7 μF
 Measured at 0.9 V output with the TCR15AGADJ variable-output LDO regulator. VDO=VIN1*1 –(VOUT1*2 –100 mV)
*1: VIN1 is an input voltage when the output voltage drops from VOUT1 by 100 mV.
*2: VOUT1 is an output voltage when VIN=VOUT+0.5 V.
