1 / 9 page US1260 3-1 Rev. 1.9 3/22/99 TYPICAL APPLICATION TYPICAL APPLICATION FEATURES FEATURES Guaranteed <1.3V Dropout at 6A (output #2) Guaranteed <0.6V Dropout at 1A (output #1) Fast Transient Response 1% Voltage Reference Initial Accuracy Built in Thermal Shutdown APPLICATIONS APPLICATIONS Providing a single package solution for GTL+ and High Speed Bus Termination Dual supply P55C ™ applications DESCRIPTION DESCRIPTION The US1260 product using a proprietary process com- bines a dual low drop out adjustable output regulators in a single package with one output having a minimum of 6A and the other one having a 1A output current capabil- ity. This product is specifically designed to provide well regulated supplies for low voltage ICs such as 3.3V to 1.5V and 2.5V supplies for the GTL+ termination and the new clock for Pentium II applications.Other applications include low cost dual supply for proces- sors such as Intel P55C ™ where 2.8V and 3.3 V are needed for the Core and the I/O supplies from the 5V input. DUAL 6A AND 1A LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR Notes: P55C is trade mark of Intel Corp. Typical application of US1260 in the Pentium ΙΙ™ design with the 1.5V output providing for GTL+ termination while 2.5V supplies the clock chip. Notes: Pentium ΙΙ is trade mark of Intel Corp. 3.3V 2.5V / 1A 1.5V / 6A C1 R1 R2 R3 R4 C2 C3 US1260 1260app7-1.0 Vctrl Vfb1 Vfb2 Gnd Vout2 Vin Vout1 1 2 3 4 5 6 7 5V C5 U1 C4 R5 PACKAGE ORDER INFORMATION PACKAGE ORDER INFORMATION Tj ( °C) 7 PIN PLASTIC 7 PIN PLASTIC 7 PIN PLASTIC TO220(T) TO263(M) POWER FLEX(P) 0 TO 150 US1260CT US1260CM US1260CP |
