GAPTEC Electronic presents the most inexpensive, non-isolated and surface mount produced SIP3 switching regulator with a minimum quiescent current of only 6mA. The LC78 is a so-called “drop-in” switching regulator which is pin-compatible with the classical LM78 linear regulator and makes a heat sink unnecessary. Therefore the use of the LC78 provides a lot of space on the PCB board. The GAPTEC product development managed to achieve an unrivaled efficiency of 95% and at the same time very small housing dimensions (L x W x H = 11.6 x 6.0 x 10.2 mm). The controller is continuous short circuit protected (SCP) and has a max. 30 mV p-p ripple and noise at 20MHz bandwidth. The temperature range is -40°C to +85°C (without derating 75°C). Input voltage range: 4.75 to 28 VDC (3.3 VDC type) and 4.5 to 42 respectively 55 VDC (5 VDC type). The product warranty is 3 years. This switching regulator series has been developed as an alternative to discrete solutions. Pricing: with a minimum order quantity of 1K = 1.49 €/piece and starting 10K = 1.39 €/piece.
