  • The TCR15AG series are available in capable of driving up to 1.5 A, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.
  • This voltage regulators are fixed output voltage type and have 46 output voltage linups from 0.65 V to 3.6 V.
  • As small ceramic input and output capacitors can be used with the TCR15AG series.


  • Ultra small package WCSP6F (0.8 mm x 1.2 mm (typ.), t: 0.33 mm (max))
  • Wide range output voltage (0.65 V to 3.6 V)
  • Fast load transient response -100 / +115 mV (typ.)@ 0.01 A⇔1.5 A, COUT = 4.7 μF
  • High ripple rejection ratio 95 dB (typ.)@1 kHz
  • Overcurrent protection function
  • Thermal shutdown function
  • Auto-discharge function
  • Inrush current reduction function ( output voltage soft start )
  • Under voltage lockout function: 0.5 V (typ.)
