| 150mA Low-Noise LDO Voltage Regulator CORPORATION CLM5205 FEATURES GENERAL DESCRIPTION The Calogic CLM5205 is a low noise, low dropout voltage regulator featuring ultra low ground current (800uA at 100mA output) and tighter than 1% initial accuracy with a logic compatible ON/OFF switching input. Designed for hand-held battery powered devices, the CLM505 is switched by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly to zero. Prolonging battery life, the ground current of the CLM5205 increases only slightly in dropout. Major features of the CLM5205 include a reference bypass pin for excellent low-noise performance, protection against reversed battery, current limiting, and overtemperature shutdown. The CLM5202 is available in several fixed voltages and an adjustable output voltage version in a small SOT-23-5 package. The pinout is smaller to the LP2980 with significantly better performance.

Electrical specifications do not apply when operating the device outside of its rated operating conditions. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, JA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: P(MAX) = (TJ(MAX) - TA) JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The JA of the MIC5205-xxBM5 (all versions) is 250oC/W mounted on a PC board. Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 3: Regualtion is measured at constant junction temperature using low duty cylce pulse testing. Parts are tested for load regualtion in the load range for 0.1mA to 150mA. Note 4: Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its normal value measured at 1V differential. Note 5: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Note 6: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 150mA load pulse at VIN = 16V for T = 10ms. Information furnished by Calogic is believed to be accurate and reliable.
