Regulator meets industrial needs

Milpitas, Calif. — Linear Technology Corp. unveiled a 100-mA industrial grade version of its LT3020 low dropout voltage regulator with guaranteed performance from -40°C to +125°C.

The new LT3020 is a very low dropout voltage regulator with input voltage capability down to 0.9 V, and a very low dropout voltage of only 150 mV at full load.

Output voltages include 1.2-V, 1.5-V and 1.8-V fixed, and an adjustable option ranging from 0.2 V to 9.5 V. The I-grade guaranteed temperature range enables a variety of applications in automotive, industrial, and instrumentation markets.

In handheld products, the LT3020's minimum input voltage of 0.9 V enables it to operate across the entire voltage range of both single cell alkaline and NiMH (1.4 V to 0.9 V) batteries — and to drive low-voltage microcontroller and microprocessor cores. Furthermore, its 150-mV dropout voltage optimizes battery run time in single cell applications with a low V(IN) to V(OUT) differential. Additionally, the LT3020 offers micropower operation with only 120 μA of quiescent current and less than 3 μA in shutdown.

The regulator optimizes stability and transient response with low equivalent series resistance (ESR) ceramic output capacitors as small as 2.2 μF. Other LT3020 features include flat typical line regulation and 0.2 percent typical load regulation from 1 mA to 100 mA of load. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3020 is available in a low profile (0.75-mm) 8-lead DFN (3mm x 3mm) package with an exposed pad and an 8-lead MSOP.

Both the LT3020IDD/-1.x (8-lead DFN) and the LT3020IMS8/-1.x (MSOP-8) are available from stock. Pricing starts at $1.60 each for both package options in 1,000s. Click here for the LT3020 data sheet.
