TS2937 500mA Ultra Low Dropout Voltage Regulator TO-220 TO-263 TO-252 SOT-223 Pin Definition: 2 (D PAK) (DPAK) 1. Input 2. Ground 3. Output General Description TS2937 of fixed-voltage monolithic micro-power voltage regulators is designed for a wide range of applications. This device excellent choice of use in battery-power application. Furthermore, the quiescent current increases on slightly at dropout, which prolongs battery life. This series of fixed-voltage regulators features very low ground current (200uA Typ.) and very low drop output voltage (Typ. 60mV at light load and 600mV at 500mA). This includes a tight initial tolerance of 2%, extremely good line regulation of 0.05% typ., and very low output temperature coefficient. Features Ordering Information Dropout voltage typically 0.6V @ Io=500mA Part No. Package Packing Output voltage trimmed before assembly TS2937CZxx C0 TO-220 50pcs / Tube -18V Reverse peak voltage TS2937CMxx RN TO-263 800pcs / 13 Reel +30V Input over voltage protection TS2937CPxx RO TO-252 2.5Kpcs / 13 Reel +60V Transient peak voltage TS2937CWxx RP SOT-223 2.5Kpcs / 13 Reel Internal current limit Note: Where xx denotes voltage option, available are Thermal shutdown protection 12= 12V Block Diagram 50= 5V 33= 3.3V Contact factory for additional voltage options.

For guaranteed specifications and test conditions see the electrical characteristics. Note 2: Maximum positive supply voltage of 60V must be limited duration (<100mS) and duty cycle (<1%). Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, Tj, the junction to ambient thermal resistance, ja, and the ambient temperature, Ta. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The effective value of ja can be reduced by using a heatsink. Note 3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 4: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current and output load current. Note 5: Output current will decrease with increasing temperature, but it will be not dropped below 500mA at the maximum specified temperature. 2/10 Version: D13
