LDK130M33R

LDK130M33R is a 300mA low quiescent current very low noise LDO in a 5 pin SOT23 package. The LDK130 low drop voltage regulator provides 300mA of maximum current from an input supply voltage in the range of 1.9V to 5.5V, with a typical dropout voltage of 100mV. It is stabilized with a ceramic capacitor on the output. The very low drop voltage, low quiescent current and low-noise features make it suitable for low power battery-powered applications. An enable logic control function puts the LDK130 in shutdown mode allowing a total current consumption lower than 1µA. The device also includes short-circuit constant current limiting and thermal protection.

• Low quiescent current (typ 30µA, 1µA in OFF mode)
• Output voltage tolerance: ±2.0% at 25°C
• Fixed output voltage of 3.3V
• Temperature range from -40°C to 125°C
• Compatible with ceramic capacitor COUT = 1µF
