Intersil Introduces New Linear Regulators

Intersil has reportedly launched a pair of low voltage, high-current, low dropout linear regulators. The ISL80102 and ISL80103 are specified for 2A and 3A output current, respectively.

 

Although technology changes rapidly each year, most LDOs currently available in the market are based on very old technology. These new parts have been designed by using new BiCMOS technology that delivers new levels of performance.

 

Intersil said these new LDOs provide the industry's fastest transient response. Such as high level of response means the output voltage is properly regulated under varying load current changes.

 

The ISL80102 and ISL80103 also feature very low dropout: 120mV dropout at 3A and 81mV dropout at 2A. These products operate from input voltages of 2.2V to 6V, and can provide supply output voltages of 0.8V to 5V on the adjustable versions.

 

According to a press release, the company is also offering fixed output voltages of 0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V as well as custom voltage options. The devices assure accurate point-of-load voltage regulation in critical applications. Shutdown current for both ISL80102 and ISL80103 is less than 1microA, and PSRR is 60dB over full-rated load current.

 

The two new LDOs can be easily placed into a low quiescent current shutdown mode. The company has included additional capabilities in the release including PowerGood status indicator, soft-start, overcurrent protection, and thermal shutdown.

 

All these capabilities make these LDOs highly reliable and customizable for a range of applications, including core power supplies for microprocessors, DSPs and FPGAs, as well as instrumentation applications, industrial and medical equipment, servers, and networking equipment.

 

Intersil has manufactured these LDOs by using a BiCMOS process, which means the products consume low quiescent current as a function of load. Their consumption contrasts sharply with that of LDOs manufactured using older bipolar processes.
