1 3mA, Low Power, Low Dropout, Linear Regulators GENERAL DESCRIPTION The low-power, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 3mA. They are perfect choice for low voltage, low power applications. An ultra low ground current (11µA at 3mA output) makes them attractive for battery operated power systems. The series also offer ultra low dropout voltage (21mV at 3mA output) to prolong battery life in portable electronics. The output voltage is preset to voltages in the range of 1.5V to 5.V. Other features include foldback current limit and thermal shut-down protection. FEATURES - Ultra-Low Dropout Voltage: 21mV at 3mA output - Low 8µA No-Load Supply Current - Low 11µA Operating Supply Current at 3mA Output - Thermal-Overload Protection - Output Current Limit - Preset Output Voltages (±1.8% Accuracy) - Output Voltage: Available in Fixed Outputs of 1.5V, 1.8V, 2.5V, 2.8V, 3.V, 3.3V, and 3.6V comes in 3-pin SOT23 and 3-pin SOT89 packages.

7 Application Notes When LDO is used in handheld products, Attention must be paid to voltage spike which would damage. In such applications, voltage spike will be generated at changer interface and VBUS pin of USB interface when changer adapters and USB equipments are hot-inserted. Besides this, handheld products will be tested on the production line on the condition of no battery. Test Engineer will apply power from the connector pin which connects with positive pole of the battery. When external power supply is turned on suddenly, the voltage spike will be generated at the battery connector. The voltage spike will be very high, it always exceeds the absolute maximum input voltage (6.V) of LDO. In order to get robust design. Design Engineer needs to clear up this voltage spike. Zener diode is a cheap and effective solution to eliminate such voltage spike. For example, BZM55B5V6 is a 5.6V small package Zener diode which can be used to remove voltage spike in cell phone design. The schematic is shown in below: Vcc Input BZM55B5V6 1uF C 1 V OUT C 2 4.7uF V OUT 7
