Toshiba Electronics has introduced the TCR3RM series of low noise ultra-compact low dropout (LDO) voltage regulators in a plastic DFN4C package measuring 1.00 mm x 1.00 mm x 0.38 mm.
RT9193 is an Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator with power consumption less than 0.01μA in shutdown mode and has fast turn-on time less than 50μs.
The MIC5205 is a low current, very low dropout voltage regulator with a maximum current of 150mA and a voltage drop of 165mV at full load. MIC5205 has an Enable pin to provide Zero-current shutdown mode.
