300 mA CMOS Low Drop-Out Regulator 風外with inrush current protection circ可照uit
The TCR3DF series are CMOS general-pur在術pose single-output voltage regula司風tors with an on/off contro兒短l input, featuring low dropout voltage,外器 low output noise voltage and low inrus信件h current.
These voltage regulators are av那相ailable in fixed output voltag男廠es between 1.0 V and 4.5 V and capable間員 of driving up to 300 mA.
They feature over-current protection, 關路over-temperature protec秒行tion, Inrush current protectio個東n circuit and Auto-discharge年新 function.
The TCR3DF series has a low dropout vol弟綠tage of 230 mV (2.5 V事還
output, IOUT = 300 mA) with l笑火ow output noise voltage o日妹f 38 μVrms (2.5 V output) and a load 農東transient response of only ⊿VOUT = ±85
mV ( IOUT = 1 mA⇔300 mA, COUT =1.0 μF).
Thus, the TCR3DF series are suitable f到了or sensitive power supply such as Anal湖跳og and RF applications.
