Features
• Output voltage (internally set): 1.0 V to 3.5 V, selectable in 0.05 V step
• Output voltage (externally set): 1.05 V to 5.0 V, settable via external resistor
• Input voltage: 1.5 V to 5.5 V
• Output voltage accuracy: ±1.0% (internally set, 1.0 V to 1.45 V output product: ±15 mV)
• Dropout voltage: 70 mV typ. (3.0 V output product, IOUT = 300 mA)
• Current consumption: During operation: 60 μA typ., 90 μA max.
During power-off: 0.1 μA typ., 1.0 μA max.
• Output current: Possible to output 1000 mA (VIN ≥ VOUT(S) + 1.0 V)*1
• Input and output capacitors: A ceramic capacitor of 2.2 μF or more can be used.
• Ripple rejection: 70 dB typ. (f = 1.0 kHz)
• Built-in overcurrent protection circuit: Limits overcurrent of output transistor.
• Built-in thermal shutdown circuit: Prevents damage caused by heat.
• Built-in inrush current limit circuit: Limits excessive inrush current generated at power-on or at the time when
the ON / OFF pin is set to ON.
For types in which output voltage is internally set, the inrush current limit time
can be changed via an external capacitor (CSS).
Inrush current limit time 0.7 ms typ.
(Types in which output voltage is internally set, CSS = 1.0 nF)
Inrush current limit time 0.4 ms typ.
(Types in which output voltage is internally set, SSC pin = open)
Inrush current limit time 0.4 ms typ.
(Types in which output voltage is externally set)
• Built-in ON / OFF circuit: Ensures long battery life.
Discharge shunt function "available" / "unavailable" is selectable.
Pull-down function "available" / "unavailable" is selectable.
• Operation temperature range: Ta = −40°C to +85°C
• Lead-free (Sn 100%), halogen-free
