Nisshinbo Micro Devices has launched the MUSES100 series – low-noise, LDO voltage regulator targeted at home audio, professional audio, and portable audio equipment. The MUSES100 series is a CMOS-based LDO regulator that operates with an input voltage range from2.5V to 5.5V, delivering an output voltage range from 1.2V to 5.0V and supporting an output currentof up to 600mA. The series ...

Infineon has introduced six automotive linear regulators, protected against 40 or 45V, and supplying 3.3 or 5V at up 500mA, some with enable, watchdog or reset circuits (see the table below). Picking the TLS820F3ELV50 as an example, it has an input range of 3 to 42V (45V abs max) and outputs 5V ±2% at up to 200mA. “These regulators are ...

Toshiba has announced 300mA LDOs in a 1 x 1 x 0.37mm DFN4D package. Quiescent current is typically 1.2μA with no load. They are “specifically aimed at applications powered by small-scale batteries [including] IoT modules, communications modules, wearable devices and other miniature equipment”, according to the company. There are over 30 devices spanning outputs of 0.8 to 5.0V, with an ...

STMicroelectronics has combined two LDOs, a CAN FD transceiver, four PWM-able high-side switches, a watchdog timer and a LIN transceiver into a single automotive-grade power IC. Called SPSB081, its aim is to provide a companion microcontroller with power, two serial interface transceivers, battery-voltage high-side load drivers and power for its peripherals. There are four devices giving 5V or 3.3V from ...

Diodes has released a 3A low-dropout low-noise voltage regulator. Called AP7179D, it has ±1% output accuracy (Vin = Vout + 300mV) across line, load and temperature, according to the company, and it drops 180mV (maximum) with 3A of load. Its low-noise reference and error amplifier contribute to 4.4µVrms typical operation at 800mV output (7μVrms at 5V), and PSSR (power supply ...

Toshiba has created a range of 36V-capable LDOs to work from USB-PD and 24V power rails. The first three devices in the planned TCR1HF series, available today, are TCR1HF18B, TCR1HF33B and TCR1HF50B with fixed outputs of 1.8V, 3.3V and 5.0V respectively. Devices are in the pipeline at 2.5, 2.8, 3.0, 3.1 and 3.2V. Maximum drop-out over the -40 to 125°C ...

Diodes has introduced AP7387Q, an LDO linear voltage regulator with a 5V to 60V input range and typically 700mV at a 100mA output current. “Thanks to its wide input voltage, the AP7387Q meets the load dump specifications of 12V internal combustion engine vehicles such as cars and 24V combustion engine vehicles such as buses, coaches, and trucks”, the company said. ...

Analogue devices has created a fast-responding low-noise low drop-out linear regulator, digitally-programmable to output various voltages between 500mV and 4.2V at up to 3A. Input range is 600mV to 5.5V. Dubbed LT3073, its output, set through three tri-level pads, can be: in 50mV increments from 500mV to 1.2V, in 100mV increments from 1.2 to 1.8V, and then 2, 2.5, 3, ...

Rohm has announced a series of 50mA low drop-out linear regulators designed to be connected directly to the vehicle battery circuits without an intermediate regulator. Called BD7xxL05G-C, their inputs operate up to 42V and can survive 45V. The parts are: BD725L05G-C (2.5Vout, 3.5Vin min), BD730L05G-C (3.0Vout, 3.5Vin min), BD733L05G-C (3.3Vout, 3.8Vin min) and BD750L05G-C (5.0Vout, 5.6Vin min). Output voltages are ...

Microchip has introduced a rad-tolerant 3A LDO (low drop-out regulator) for LEO (low-earth orbit) and other space appliations. MIC69303RT is available for prototype sampling in both plastic and hermetic ceramic packaging. The regulator is based on an existing COTS (commercial off-the-shelf) devices and operates from between 1.65 to 5.5V and can deliver as low as 500mV, with drop-outs as low ...
