PD-97259 Adjustable Positive Linear Regulator Thru-Hole (TO-257AA) OM7602ST OM7602NT 1.5A Product Summary Part Number Input Voltage Range Adjustable Output Voltage Package OM7602ST 4.25V to 41.25V 1.2V to 37V TO-257 (Isolated) OM7602NT 4.25V to 41.25V 1.2V to 37V TO-257 (Non-Isolated) TO-257AA Description This three terminal positive regulator is supplied in a hermetically sealed metal package. All protective features are designed into the circuit, including thermal shutdown, current-limiting, and safe-area control. With heat sinking, these devices can deliver up to 1.5 amps of output current. This unit also features output voltages that can be trimmed from 1.2 volt to 37 volts using external resistors.

VOUT = 1.25V(1 + (R2/R1)) + IADJ(R2) Since IADJ is not controlled to less than 100A, the error associated with this term is negligible in most applications.
