A built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. In addition to the type in which output voltage is set inside the IC, the type for which output voltage can be set via an external resistor is added to a lineup.


Features:

• Output voltage (internally set): 0.9 V to 6.0 V, selectable in 0.05 V step

• Output voltage (externally set): 1.0 V to 9.0 V, settable via external resistor(HSOP-8A, HSOP-6 and HSNT-8(2030) only)

• Input voltage: 2.5 V to 10.0 V

• Output voltage accuracy: ±2.3% (Tj = −40°C to +105°C)

• Dropout voltage: 0.09 V typ. (2.6 V output product, at IOUT = 200 mA)

• Current consumption: 

During operation: 120 μA typ., 150 μA max. (Tj = −40°C to +150°C)

During power-off: 0.1 μA typ., 4.5 μA max. (Tj = −40°C to +105°C)

• Output current: Possible to output 500 mA (at VIN ≥ VOUT(S) + 1.0 V)*1

• Ripple rejection: 60 dB typ. (at f = 1.0 kHz)

• Built-in overcurrent protection circuit: Limits overcurrent of output transistor.

• Built-in thermal shutdown circuit: Detection temperature 170°C typ.

• Built-in soft-start circuit: 

Adjusts output voltage rising time at power-on or at the time when

ON / OFF pin is set to ON.

Adjustable type: E / F / G / H type, tSS = 6.0 ms typ. (CSS = 10 nF)

Soft-start time can be changed by the capacitor (CSS).

Fixed type: A / B / C / D type: Fixed to tSS = 1.0 ms typ.

• 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 +105°C

• Lead-free (Sn 100%), halogen-free

• AEC-Q100 qualified*2

*1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large.
