TD1801
ＴＡＩＤＩＡＮ ＫＥＪＩ Low power consumption,Low ESR Cap.Compatible TD1801 Series
General Description
Features
TD1801 series are highly precise, low power
consumption, high voltage, positive voltage
regulators manufactured using CMOS and laser
trimming technologies .The series provides large
currents with a significantly small dropout voltage.
The series is compatible with low ESR ceramic
capacitors .The current limiter’s foldback circuit also
operates as a short protect for the output current
limiter and the output pin.

2.VOUT (E) ：Effective Output Voltage ( le. The output voltage when “VOUT (T)+1.0V”is provided at the Vin pin while
maintaining a certain Iout value.)
3.Vdif ：VIN1 –VOUT (E)’
VIN1 ：The input voltage when VOUT(E)’ appears as input voltage is gradually decreased.
VOUT (E)’=A voltage equal to 98% of the output voltage whenever an amply stabilized Iout {VOUT (T)+1.0V}
is input.
