STMicroelectronics (ST) has released the STLQ020, a Low-Dropout (LDO) voltage regulator that allows for wider application by mitigating the trade-off between standby current, output power, dynamic response, and package size.

The STLQ020 delivers both high performance and power efficiency in a small size, making it ideal for battery-powered consumer products such as smartphones, tablets, smartwatches, audio or media devices, and wearables. It can also extend battery life in applications such as IoT devices like smart meters and wireless sensors, healthcare devices like wearable monitors, and industrial applications like factory automation or sensor networking.

STLQ020 has a standby current (Iq) of only 300nA, can supply loads of up to 200mA through excellent regulation and PSRR (Power-Supply Rejection Ratio) and transient response characteristics, and can be used in small packages such as 0.8 x 0.8mm Flip-Chip4.

These unrivaled characteristics are attributed to the STLQ020's dedicated low-power design and adaptive bias circuit technology, which enable stable output with high PSRR and fast response speed. Additionally, it has a low dropout voltage of 160mV (typical) at maximum load, which can extend the operating time of the equipment along with battery discharge. In addition, STLQ020 can extend the coin cell replacement cycle for short-cycle applications such as remote sensors through the advantage of a 5nA logic-controlled shutdown mode.

Meanwhile, the STLQ020 features an input voltage range of 2.0 to 5.5V, allowing it to be powered directly from the appropriate battery voltage (VBAT) or logic rails. The output voltage can be set from 0.8 to 4.5V using either a fixed output or a variable output version. The fixed output voltage can be selected in increments of 50mV.
