DESCRIPTION
range even if the input voltage or load voltage fluctuates, by integrating a high-gain error
temperature-compensating constant-voltage diode on a single chip.
FEATURES
• Wide output voltage variable range: Vo = 4.5 to 30 V, V
• Excellent load stability: 0.02%
• Good ripple rejection ratio: 0.003%/V
