MC7808CDTRKG

MC7808CDTRKG Description

The MC7808CDTRKG from onsemi is a fixed-output linear voltage regulator designed to deliver a stable 8V DC output with a maximum input voltage of 35V and an output current capability of 1A. Packaged in a DPAK (TO-252) surface-mount form factor, this regulator is optimized for space-constrained applications while ensuring reliable performance. Its low dropout voltage (2V typical at 1A) and 62dB PSRR (120Hz) make it suitable for noise-sensitive circuits. The device operates over a wide temperature range (0°C to 125°C) and includes over-temperature and short-circuit protection, enhancing system robustness.

MC7808CDTRKG Features

• Fixed 8V Output: Ensures precise voltage regulation without external adjustments.
• High Input Voltage Tolerance (35V Max): Accommodates fluctuating input sources.
• 1A Output Current: Supports moderate power loads with minimal heat dissipation.
• Low Dropout Voltage (2V @ 1A): Improves efficiency in low-input scenarios.
• 62dB PSRR (120Hz): Effectively suppresses input ripple for clean output.
• Protection Features: Over-temperature and short-circuit safeguards enhance reliability.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• Surface-Mount DPAK Package: Ideal for automated assembly and compact designs.

MC7808CDTRKG Applications
