SI3025

The SI3025 is designed as the low-voltage, high-current 2.5 V linear regulator that incorporates a monolithic low-level reference and control circuit with a high-current pnp transistor in a power multi-chip module. Also SI3025 is supplied in a fully molded 8-lead miniature surface-mount package (tape and reel) with enhanced power-dissipating qualities.

Features of the SI3025 are:(1)1 A output current; (2)low dropout voltage; (3)LSTTL/CMOS-compatible on/off control less than 1 A "sleep" current; (4)internal foldback overcurrent limiting; (5)internal thermal protection; (6)surface-mount package.

The absolute maximum ratings of the SI3025 can be summarized as:(1)Input Voltage, VI: 16 V;(2)Supply Voltage, VS: 16 V;(3)Continuous Output Current, IO: 1.0 A;(4)Logic Input Voltage, VE: VS;(5)Package Power Dissipation: See Graph;(6)Output Junction Temperature: +150°C;(7)Operating Temperature Range: -30°C to +100°C;(8)Storage Temperature Range: -30°C to +150°C.

The electrical characteristics of SI3025 can be summarized as:(1)Output Voltage: 2.45 to 2.55 V;(2)Output Volt. Temp. Coeff.: ±0.3 mV/°C;(3)Overcurrent Limit: 1.2 to 1.5 A;(4)Line Regulation: 2.0 to 10 mV;(5)Load Regulation: 10 to 20 mV;(6)Dropout Voltage: 220 to 400 mV;(7)Ground Terminal Current: 1.7 to 2.5 mA;(8)Rejection Ratio: 57 dB;(9)Thermal Protection Temp: 135 to 150 °C;(10)Thermal Resistance: 36 °C/W.
