Rohm Semiconductor launches high capacity LDO regulator ICs based on Nano Cap technology

AP7369Q is a series of 45V input low-drop-out linear regulators from Diodes that can provide up to 150mA to a load. Quiescent current can be as low as 2.1µA and, depending on variant, the output is fixed at 2.5V, 3.3V or 5V. “The device provides a very fast response against line voltage transient and load current transient, and ensures no ...

Diodes has created a quiet low-drop out (LDO) linear regulator for powering ADCs, DACs, VCOs and phase-locked loops. “With up to 90dB PSRR [power supply ripple rejection], and output noise at 8μVrms, the AP7372 helps designers mitigate the effects of input source noise and meet output ripple and noise targets,” according to the company, which sees it being used in ...

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called NEH7100BU, it can mediate between a harvesting power source, a USB charger, a battery (or capacitor) and the load. To maximise power extracted from photovoltaic cells, which have variable output impedance, and embedded hill-climbing algorithm homes-in on the best operating point ...

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 ...
