ILC7080/81 are 50 or 100mA low dropout (LDO) voltage regulators designed to provide a high performance solution to low power systems.
The ILC7080/81 series provides low‑dropout voltage regulation for portable wireless devices. Available in fixed‑voltage versions (2.5 V‑5.0 V) and an adjustable version (ILC7081), the regulators deliver 50 mA or 100 mA output current with ultra‑low quiescent current and excellent noise performance.
The datasheet includes pin assignments, absolute maximum ratings, electrical characteristics, shutdown operation, protection features, layout guidelines and ordering information to help designers integrate the LDO into compact SOT‑23‑5 packages.
| Output current | 50 mA or 100 mA |
|---|---|
| Dropout voltage | 0.1 mV at 1 mA load |
| Ripple rejection (1 kHz) | 85 dB |
| Ground pin current (0.1 mA load) | 95 pA |
| Maximum package power dissipation | 250 mW (SOT‑23‑5) |
| Operating temperature range | -40 °C to +85 °C |
| Maximum junction temperature | +150 °C |
| ON/OFF pin turn‑off voltage | ≤ 0.4 V |
Apply 0.4 V or less to the ON/OFF pin (pin 3) to turn the device off; applying 2 V enables it.
Typical dropout is about 0.1 mV per milliamp of load current.
