STMicroelectronics revealed the STLQ020 low-dropout (LDO) voltage regulator and claims to relieve the familiar trade-offs between quiescent current, output power, dynamic response, and package size, to give designers extra freedom.
The STLQ020 by STMicroelectronics is a combination of small size with high performance and energy efficiency and is ideal for use in battery-powered consumer products like smartphones and tablets, smart watches, audio or media devices, and wearables.
It helps extend battery life in IoT endpoints such as smart meters and wireless sensors, healthcare devices like wearable monitors, and industrial applications such as factory automation or sensor networking.
the STLQ020 is available in a choice of compact packages reaching as small as a 0.8mm x 0.8mm flip-chip4. It draws just 300nA quiescent current (Iq), and is capable of supplying up to 200mA to the load with excellent regulation, power-supply rejection (PSRR), and transient response states STMicroelectronics.
This unique combination of attributes stems from the STLQ020’s dedicated low-power design and adaptive bias circuitry, which ensures fast response and a stable output with high PSRR.
Further, the dropout voltage as low as 160mV (typical) at maximum load enables longer equipment runtimes as the battery discharges. Also, with the advantage of its 5nA logic-controlled shutdown mode, the STLQ020 can extend the interval between coin-cell replacements in low-duty-cycle applications like remote sensors.
With an input voltage range of 2.0V-5.5V, the STLQ020 can be powered directly from a suitable battery voltage (VBAT) or logic rail. The output voltage can be set between 0.8V and 4.5V, with either fixed-output or adjustable-output versions available. The fixed output voltages are selectable in 50mV increments.
