TDA3668中文资料Very low dropout voltage/quiescent current 5 V regulator with overvoltage switch off数据手册恩XP规格书

描述 Description

GENERAL DESCRIPTION
The TDA3668AT is a fixed 5 V voltage regulator with a very low dropout voltage and quiescent current, which
operates over a wide supply voltage range.FEATURES
• Fixed 5 V, 100 mA regulator
• Supply voltage range up to 50 V
• Very low quiescent current of 15µA (typical value)
• Very low dropout voltage
• High ripple rejection
• Very high stability
– Electrolytic capacitors: Equivalent Series Resistance (ESR) < 38Ωat IREG≤25 mA
– Other capacitors: 100 nF at 200µA≤IREG≤100 mA.
• Pin compatible family TDA3661 to TDA3676
• Protections:
– Reverse polarity safe (down to−25 V without high reverse current)
– Negative transient of 50 V (RS=10Ω, t < 100 ms)
– Able to withstand voltages up to 18 V at the output (supply line may be short-circuited)
– ESD protected for all pins
– DC short-circuit safe to ground and VPof regulator output
– Temperature protection at Tj 150°C
– Load dump protection, which will switch off VREG during load dump.
