Rohm Electronics' latest CMOS low dropout regulator (LDO) is said to feature an output current of 150mA and high output voltage accuracy (±1 per cent).

Furthermore, the VCSP60N1 LDO regulator, which is part of Rohm's BHxxRB1WGUT series, offers a low drop out voltage of 100mV (at I/O=100mA), and low power consumption of 34µA and 0, during operation and standby, respectively (utilizing Bi-CMOS processes).

Rohm added that the high electrostatic discharge resistance (5kV) combined with built-in overcurrent and thermal protection circuits ensure a high degree of reliability in any environment.

The company's LDO regulator series is offered in an ultra-compact 4-pin CSP package—possessing high heat radiation characteristics (540mW), the company said. The VCSP60N1 LDO regulators are available in different output voltages (1.5-, 1.8-, 2.5-, 2.8-, 2.9-, 3-, 3.1- and 3.3V), making them practical for use in a variety of portable applications. Other characteristics include a 63dB ripple rejection rate and compatibility with ceramic capacitors. Pricing for the VCSP60N1 series LDO regulators is Rs.8.84 (20 cents) each (minimum purchase of 3,000 pieces) with 12 week lead time ARO.
