LDO регуляторы напряжения MAX1982EUT+T

Фиксированный стабилизатор с малым падением напряжения , 1.25В-5.5В (Vin), 350мВ, 1.2В/300мА

The MAX1982EUT+T is a low voltage, low dropout linear regulator with external bias supply in 6 pin SOT-23 package. The 5V bias supply drives gate of internal N-channel pass transistor making device ideal for applications that require low voltage outputs from low voltage inputs. It delivers 1.2V (±3%) at 300mA from an input voltage of 1.25V to 5.5V. It includes a current-limit and thermal shutdown that protects regulator in event of a fault condition. It is used in notebook computers, VID power supplies, PDAs, cell phones and low dropout regulators with external bias supply.

• Supply voltage range is 1.25V to 5.5V
• Operating temperature range from -40°C to 85°C
• No minimum load current required
• Power-good (PGOOD) open drain output with 1ms rising edge propagation delay
• Low supply current (IBIAS + IIN = 165µA typ)
• 5µA (max) shutdown supply current
• Dropout voltage of 350mV (max) at ILOAD = 300mA
